CHARLES F. MILHOLEN, OF KANNAIEOLIS, NORTH CAROLINA.

GEARING.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed December 27, 1919. Serial No. 347,656.

To all whom it may concern:

Be it known that I, CHARLES F. MIL- HOLEN, a citizen of the United States, residing at Kannapolis, in the county of Cabarrus and State of North Carolina, have invented certain new and useful Improvements in Gearing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in gearing and has for its primary object the provision of means which is capable of increasing or decreasing the speed or revolution of a devicethat is driven by a power source without utilizing a great amount of power in accomplishing such a result.

Another object of this invention is the provision of a gearing of the above stated character, which shall be simple, durable and eiiicient, and which may be manufactured and sold at a comparatively low cost.

lVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of a gearing constructed in accordance with my invention, Y

Fig. 2 is a plan view of the same,

Fig. 3 is a longitudinal sectional view taken on line 3-3 of Fig. 2,

Fig. 4: is a transverse sectional view taken on line 44 of Fig. 2.

Referring in detail to the drawing, the numeral 1 indicates a base having spaced bearings 2 at one end which rotatably support a shaft- 3 which has secured to one end a com )aratively large gear 4:. The gear 4 is in t e form of a circular plate 5 having formed on one face adjacent its periphery a plurality of circularly arranged and relatively spaced pins 6 adapted to form the teeth to said gear 4:. The hub of the gear 4 is of a considerable length and the end shaft 3 terminates within said hub and the hub also receives the end of a shaft 7. The shaft 7 is rotatably supported by bearings 8 and has secured thereto adjacent the gear 4 a spider 9 which has journaled in its ends stub shafts 10. Pinions 11 are secured to one of the ends of the stub shafts and mesh wlth the pins 6 of the gear 4, while the other ends of the stub shafts have secured thereto pinions 12 which mesh with a double gear 13. The double gear 18 is journaled on the shaft 7 adjacent the spider and includes a straight gear and a bevel gear of an integral structure, and the bevel gear meshes with a bevel gear 14 journaled on the end of a stub shaft 15. The stub shaft 15 is arranged at right angles to the shaft 7 and is supported by bearings 16 carried by the base A bevel geanl? meshes with the bevel gear 14 and is secured to the shaft 7, whereby upon rotation of the shaft 7 by a power source the shaft 3 will be compelled to rotate approximately one and three-quarters times to one complete revolution of the shaft 7. When it is desired to decrease the number of revolutions to a device from a power source, the power source is connected to the shaft 3 which permits a step down in rotation to the device 'driven by the power source.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scopeof the invention as claimed.

Having thus described my invention, what I claim is A gearing including a base, alining shafts journaled to said base, alantern gear secured to one of said shafts, a spider secured to the other shaft, stub shafts carried by said spider, pinions secured to the ends of the stub shafts and some of said pinions meshing with the lantern gear, a double pinion journaled on the last named shaft and meshing with the other pinions of the splder, a reverslng gear rotatably supported by the base and meshing with the double gear, and a pinion secured to the last named shaft and in mesh with the reversing pinion.

In testimony whereof I affix my signature in presence of two witnesses.
